We can get behind most family traditions around the holidays, like opening one present on Christmas Eve or leaving milk and cookies out for Santa Claus, but there’s one tradition that just makes absolutely no sense and it’s performed by—you guessed it—the Royal Family. What is this strange and bizarre tradition that Harry, Meghan, Will, Kate, Charles, Camilla, and The Queen (and now maybe even Doria) will have to participate in? It’s something that most families would likely skip.

According to Cosmopolitan, the Royal Family supposedly gets weighed before and after Christmas dinner. Say what? This fun fact was shared in the most recent issue of Grazia. Cosmo reports, “They claim the tradition dates back to King Edward VII‘s reign. Apparently, King Edward VII was intensely concerned about people’s health and whether or not they were eating enough on Christmas.”

Rumour has it that this tradition still lives on today using antique scales so it’s unclear as to whether or not the weigh-ins are accurate, but that’s beside the point. Other royal Christmas traditions that don’t seem quite as weird? Exchanging gag gifts, watching a soccer game played by William, Harry, estate workers and nearby villagers, Christmas Eve tea, listening to The Queen’s speech and attending two church services.

The good thing is that the whole weigh-in thing is apparently optional and no one is forced to jump on the scale after eating a plate full of turkey. They wouldn’t want to scare off Doria on her first Christmas with the Queen, after all.
